pom. addition to scalar analysis, Ma, the magnitude of the ment of a force about a specified axis, can be found ng the triple scalar product Part C An old wooden telephone pole with a single cross member was blown off center during a recent storm. To temporarily stabilize the telephone pole, a repair crew has attached a cable from the end of the cross member to an eye-ring stake anchored in the ground. (Figure 3) If the origin O of a coordinate system is placed where the pole meets the ground, the point where the cross member is attached to the pole is A(-2.80, 2.20, 23.9) ft and the point where the cable is attached to the end of the cross member is B(-2.80, -2.80, 26.9) ft. The cable's direction is {1.00i – 1.00j – 1.00k} and it has a tension of 135 lb . What is Ma, the moment that tends to twist the telephone pole due to the tension in the cable applied at point B?
